Service Interval Indicator
A service interval message will automatically appear in the message center when a pre-determined distance or time before a scheduled service is reached. The kilometer or mileage countdown is controlled by the engine management system and is adjusted to allow for driving style and conditions to gauge when the appropriate service becomes necessary.
Service Interval Message
The service indicator displays information calculated by the engine control module (ECM) to the remaining distance to the next service based on the amount of fuel used since the last service interval indicator reset.
The ECM counts down the distance to engine service and the instrument cluster rounds this down to the nearest 50 miles. The fuel used based count down starts from 3200 miles displaying the required figure in the trip computer message center, for example 'Service Required in 1950 miles'.
When the ECM has calculated the distance to service is 0 miles, the ECM will request the instrument cluster to display 'Service Required' in the message center.
The ECM also monitors and calculates when the time to the next oil service is required, 'Service Required' is displayed in the message center. This message takes priority over the distance to service calculation.
The service information is displayed in the message center for 4 seconds at each ignition cycle. There is no minus figure if the service distance is exceeded, 'Service Required' is displayed until the ECM service counter is reset using an approved diagnostic system.
